Lighting
The constructors need to provide sufficient lighting for the surrounding area of the demolition site so that people can see obstructed materials from the operation.
Prevention of falling materials
In case of planning and management of demolition, it should provide the protection of accidentally falling materials from the work. For example, there must be the covered shelter walkway along the area near the demolition site wide enough for the flow and smooth traffic with sufficient natural lighting or light bulbs to ensure all time security.
In case that there is the transfer of materials to the ground, there must be the prepared area for this with the enclosed fencing to prevent people from the access to this area.
